The next two decades will see fundamental shifts in the availability, prices and sources of fuel and alternative power systems, predicts Takeshi Uchiyamada, executive vice president of product planning for Toyota Motor Co.
Toyota expects 90% of the world vehicle fleet to be powered by some variant of an internal combustion engine in 2020—most of them hybrid-electric rather than IC-only configurations. Uchiyamada estimates that fewer than 10% of new vehicles sold in 20 years will use all-electric or fuel cell systems.
World oil production is likely to peak in about 10 years, as output of liquid fuels synthesized from coal, natural gas and biomass grows. Hydrogen production is not expected to significantly ramp up until 2030, along with an expansion in nuclear energy.
Uchiyamada made the forecasts and outlined Toyota’s corresponding powertrain strategy at a press briefing this week during the North America International Auto Show in Detroit.
Uchiyamada says conventional hybrids and more advanced models with plug-in capability are likely to dominate midsize passenger cars. All-electric systems are most likely in small, urban commuter vehicles, and hydrogen fuel cells are expected to emerge in long-range personal-use vehicles and heavy trucks.
Battery development will play a vital role in Toyota’s hybrid/electric/fuel cell initiatives. Although performance and basic material costs favor lithium-ion batteries, the technology is twice as expensive as nickel-metal-hydride systems because of its more complex manufacturing process and operating complexity. Koei Saga, who heads Toyota’s advanced technology efforts, says Toyota is pursuing chemistries that use lower-cost materials in place of current cobalt-based electrolytes.
The company unveiled its new FT-CH concept at the Detroit show and plans to introduce it in the U.S. and other worldwide markets in coming years. Aimed at younger, less affluent customers than the Prius attracts, the FT-CH rides on a 100-inch wheelbase. The four-seater will weigh less than 3,000 lbs and be more fuel-efficient than the company’s 50-mpg Prius hybrid.
